\ HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,728, dated January11, 1887.

Original application filed August 4,1883, SerialNo. 102,762.

Divided and this application filed August 18, 1885 Serial No. 174,698.(No model.)

To all whom it may concern.-

Be it known that 1, ANDREW STARK, a citizen of the United States,residing at Chicago, in the county of Cook and Stateof Illinois, haveinvented certain new and useful Improvements in Harvesting-Machines,which are fully set forth in the following specification.

' junction.

This application is a division of my application filed August 4, 1883,No. 102,762.

The invention consists in certain novel features of construction adaptedto secure in a harvesting-machine frame rigidity and compactness ofstructure, as hereinafter described, and set forth in the claims.

In the drawings, Figure 1 is a plan of my harvester-frame. Fig. 2 is afront elevation of the same. Figs. 3' and 4 are respectively a rearelevation and a stubble-side elevation of the inner segment, showing itsconnection with the finger-bar and main frame.

A is the mainframe bar,formed, preferably, of angle-iron, extending in asingle continuous piece partly around the driving'wheel from the point 1by way of the angles 2, 3, 4, and 5t0 the point 6." From the point 3,near the intersection with the draft-pole,this frame has the portion atextending diagonally backward in a direct line to the point 2, near itsjunction at 1 with the finger bar A and thence crosses the latter atright angles, in order to afford a rigid junction therewith, the twoparts being firmly bolted together at said formed of angle-iron,is'rigidly secured also at S to a suitable bracket, 0 formed on theinner segment, 0*. The bar A is bolted to the frame-bar A at the points14 and 9,and to the segment 0 at 16 and 17, and at 19 it is bolted bar Aat 7, and thence extends to the cross-' bar A, to which it is secured at13.

The parts thus far described constitute the main frame, adapted to carrythe usual driving, cutting, and conveying mechanisms, and

The finger-bar A, also preferably 7 an automatic binder, whose frame,support-- ing and containing the usual table and mechanism of suchmachines, is designed to be secured to the said main frame above thebars A* and A ,in the rear of the line of the fingerbar A This mainframe is sustained upon the driving-wheel C and the grain-wheel b, thedesign being as nearly as possible to balance the frame on these wheels,the pole upheld by the horses and locked rigid with the frameconstituting a third support.

The main frame is sustained upon the driv ing-wheel in the usual mannerby means of the segments 0 and secured to the frame, and

wheel engaging with. the racks on said segments; The outer segment, 0',is fastened to y the pinions 0 on the axle of the driving-.

the frame-bar A, and the-inner segment, 0 is bolted to the end of thefinger-bar and to the cross-bar A, as above described.

The draft-pole A is locked to the main frame rigidly, butpreferably madecapable of adj ustment. I prefer to give it its principal attachment tothe frame at or directly above the stubble end of the finger-bar, andfor that purpose I provide the hinge F, one member of which, F, isbolted directly to the finger-bar and the other member, F is firmlysecured to the end of the pole. The form of each member is adapted tothe shape of the part to which it is to be secured, and the details ofstructure of the hinge are such as fit the hinge to serve certainpurposes in adjusting the machine.

From the hinge F the pole extends slightly upward over the frame-bar A,near to the cross-bar A, and under the iron loop Fflwhich is secured tothe frame-bar A and to the crossbar A. Near the loop F the pole is adjustabl y locked to the frame-bar A".

The advantages of the several features of. construction above describedI will now state, in order that it may be understood what de tails arematerial and what may be varied without losing the advantages which itis the purpose of this invention to secure.

First. By extending the finger-bar toward t-he'drive-wheel and joiningit directly to the inner segment, said inner segment being rigidlybraced and further serve to stiffen the frame,

and particularly the segment which guides the drive-wheel is therebyenabled to keep the gear-rim of the latter properly in mesh with thedriving-pinion, whose bearing will be obtained on the main frame; hence,however the forms and proportions of the parts may bevaricd, theabove-stated features of construction should be retained.

Second. The main frame, the inner segment, and the finger-bar being thusmutually interconnected, the draft-pole, connected to the finger-barnear its junction with the segment and near to the junction of thesegment with the frame, will draw the machine with the least possibletendency to strain any of its joints or distort any of its shafts orcramp them in their bearings.

Third. The diagonal portion a of the framebar A being in approximately adirect line from the junction of said frame-bar with the finger-bar toits intersection with the pole under the loop F enables the machine tobe turned by means of the pole with the least possible tendency to sagthe cutter-bar or wrench the frame.

The mechanism for adj usting the platform and the relation of the polethereto, herein partly shown and described, are the subject of my saidapplication No. 102,762, filed August 4, 1883, and the same are notherein claimed. Neither do I claim herein the inner segment finger-barand grain-wheel guide all rigidly secured together, as partly shownherein, because I have claimed such structure in my application No.147,143, filed November 3, 1884.

1. In aharvesting-machine, the combination of a rigid main frame adaptedto carry the driving mechanism, the inner segment axleguide,and a rigidfinger-bar, each of said parts secured rigidly to both the others,substanof an iron main frame rigidly secured to the finger-bar andextending thence around the front outer side and rear of thedrive-wheel, a cross-bar at the inner side of said wheel rigidly securedat front and rear to said iron frame, and the inner guiding-segment forthe main axle rigidly and'directly secured to both the finger'bar andthe said cross-bar, substantially as set forth.

4. In a harvesting-machine, the combination of an iron frame extendingaround the front outer side and rearof the drive-wheel, a crossbar atthe inner side of the wheel and rigidly secured at front and rear to thesaid iron frame, and theinnerguiding-segmentfor the main axle securedrigidly and directly both to the fingerbar and thecross-bar,substantially as set forth.

5. In a harvesting-machine, the main frame consisting of the continuousiron bar A, hav- "ing the portion at extending diagonally from a pointnear the intersection of said bar with the draft-pole to a point nearthe finger-bar, the crossbeams A and A bolted rigidly to said bar 'A,and the finger-bar A, rigidly secured to,the said iron bar near the endof the diagonal portion a, and to the said cross beams, substantially asand for the purpose set forth.

6. In a harvesting-machine, the main frame consisting of thecontinuousiron'bar A,secured at one end to the finger-bar near the heelof 5 the cutter-bar, thence extending in an approxi- I mately directcourse to its intersection with the draft-pole, and thence around thefront outside and rear of the drive-wheel, in combination with thecross-beams A and A secured to the front and rear portions of said ironbar A, the fingerbar A, and the rear sill,

A, the last two being secured to both of said cross beams, substantiallyas and for the purpose set forth.

7. In a harvesting-machine, the rigid main frame supported at one enddirectly upon the main axle, segment axle-guides rigidly secured to theframe, the finger-bar rigidly and directly secured to the innersegment-guide, and a pole connected to the finger-bar and locked rigidwith the main frame, all combined and operating as and for the purposeset forth.

In testimony whereof I have hereunto set my hand, in the presence of twowitnesses, at Ohicago, Illinois,this 30th day of June, A. D. 1885.
